Due to the arrangement of the fixed contacts (earth - busbar), it is not necessary to interlock the CLOSE and EARTHING functions. During the closing operation, the operating shaft with the moving contact blades changes from the “OPEN” to the “CLOSED” position. The force of the spring-operated mechanism ensures a high closing speed and a reliable connection of the main circuit. Opening operation During the opening operation, the arc is caused to rotate by the arc-suppression system, thus preventing the development of a fixed root. This very effective arc extinction provides short arcing times. The isolating distance in gas established after opening satisfies the conditions for isolating distances according to IEC/EN 60 265-1 / VDE 0671102 and IEC/EN 62 271-1 / VDE 0671-1. Earthing operation The "EARTHING" operation is implemented by the turning movement of the operating lever (rotation, if required) from the "OPEN" to the "EARTHED" position. Operating mechanisms for the three-position switch Common features • Mechanical endurance of more than 1000 operating cycles • Manual operation with the help of a slip-on operating lever • Option: Motor operation of the disconnecting function • Control board with accordingly cut-out switching gate prevents the three-position switch-disconnector from being switched directly from the CLOSED via the OPEN to the EARTHED position. • Two separate actuating openings are provided for unambiguous selection of either the load-break or make-proof earthing functions. • Operation via rotary movement, operating direction according to IEC/EN 60 447 (VDN/ VDEW recommendation). The switching movements are performed independently of the operating speed. Features of springoperated/stored-energy mechanism During the charging process, the closing and opening springs are charged. This ensures that the switch-disconnector/fuse combination can switch off all types of faults reliably even during closing. Closing and opening is done via pushbuttons after removing the operating lever, and is therefore identical with the operation of circuit-breaker operating mechanisms. An energy store is available for tripping by means of an operating HV HRC fuse or via a shunt release (f-release). After the HV HRC fuse has tripped, a red transverse bar appears on the "fuse tripped" indicator. Manual operation for the EARTHING function with the help of a slip-on operating lever.

First, the operating springs are charged with the "spring charged" operation. Then, closing and opening is done via separate pushbuttons. An energy store is available for the opening process when an HV HRC fuse or a shunt release (f-release) trips. No additional charging process is required for the energy store. This energy store is already charged by switching from the "spring not charged" position to the "spring charged" position. This pre-charged energy store ensures that the switch-disconnector/fuse combination can switch off all types of faults reliably even during closing. After the HV HRC fuse has tripped, a red transverse bar appears on the "fuse tripped" indicator. Generally, the switchgear is equipped with an operating lever ejection system, which means that, after charging the springs, the operating lever is ejected, thus preventing it from being left inserted accidentally. On the customer's request, the operating lever ejection system can be ommitted. ATTENTION! Risk of injury! When charging the spring, the operating lever is inserted in the actuating opening. If no operating lever ejection system is available, the operating lever rotates and can thereby injure the operator. Ö Remove operating lever before charging the spring. 14 Revision 06 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * 500-8384.9 Description Sequence 1 2 3 4 OPEN CLOSE OPEN Operation Charging the springs Switch position OPEN Position indicator "Spring charged" indicator Closing spring not charged charged not charged not charged Opening spring not charged charged charged not charged Equipment Mechanism operation Operating levers for charging the springs of the switch-disconnector and the make-proof earthing switch.

Remote electrical tripping of the three-position switch-disconnector is possible via the magnet coil, e.g. transformer overtemperature tripping. To avoid thermal overloading of the shunt release in the event of a continuous signal that may be applied, the shunt release is switched off via an auxiliary switch which is mechanically coupled with the three-position switch-disconnector. In transformer panels, continuity at the shunt release can only be tested when the operating lever is removed. Auxiliary switch (optional) The operating mechanism of the three-position switch-disconnector can be optionally equipped with an auxiliary switch for the position indication. A motor operating mechanism is equipped with an auxiliary switch as standard. • For switch-disconnector function: CLOSED and OPEN: 1 NO + 1 NC + 2 changeover • For earthing switch function: CLOSED and OPEN: 1 NO + 1 NC + 2 changeover Fig. 8: Wiring 16 Auxiliary switch in the operating mechanism of the three-position switch-disconnector, for example in the ring-main feeder Auxiliary switches, motor operating mechanisms or shunt releases are wired to terminal strips. The terminal strips are feeder-related and located over the operating mechanism assembly of the associated feeder. Customer-side cable routing is made from the side, if required from above to the terminal strip arranged at the operating mechanism assembly.

In the event that fuse tripping fails, e.g. if the fault current is less than Imin, or if the fuse has been inserted incorrectly, the fuse box is protected by thermal protection. The overpressure generated by overheating trips the switch via a diaphragm in the cover of the fuse box and via the articulation. This breaks the current before the fuse box incurs irreparable damage. This thermal protection works independently of the type and design of the HV HRC fuse used. Like the fuse itself, it is maintenance-free and independent of any outside climatic effects. Schematic sketches for fuse tripping Fuse-link in service condition Fuse tripped by striker Fuse tripped by overpressure, e.g. if fault current is less than Imin and if HV HRC fuse has been inserted incorrectly Furthermore, the specified HV HRC fuses release the striker depending on the temperature and trip the switch-disconnector as early as in the fuse overload range. Impermissible heating of the fuse box can be avoided in this way. 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 27 Description 7.7 Cable connection ATTENTION!

This offers a high flexibility for the creation of switchgear configurations whose functional units are lined up in any order. Local installation and lining up is done without gas work. Lining up takes place as follows: • By the busbar couplings on the medium-voltage side. Tolerances between adjacent panels are compensated by spherical fixed contacts and the movable contact coupling with degrees of freedom in all axis directions. • By safe dielectric sealing with screened silicone couplings that are externally earthed and adjustable to tolerances. These silicone couplings are pressed on with a defined pressure when the panels are interconnected. • On free busbar ends, screened dummy plugs are inserted, each of which is pressed on through a metal cover. A common protective cover with a warning is fixed over all three covers. • By centering bolts for easier switchgear installation and fixing of adjacent panels. • By bolted panel joints with defined stops for the distances between adjacent panels and the associated pressure of contact pieces and silicone couplings. Switchgear installation, extension or replacement of one or more functional units requires a lateral wall distance ≥ 200 mm. 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 31 Description a s d f g h Centering bolt a s d f Side wall of vessel Right side wall of vessel Tension spring for earthing Contact piece Silicone coupling Left side wall of vessel Fig. 24: Lining up via busbar coupling Clamping cover for dummy plugs Silicone dummy plug Busbar termination cover Fig. 25: Switchgear end wall with dummy plug 7.9 Current and voltage transformers Current and voltage transformers Current transformers • According to IEC 60 044-1/ VDE 0414-44-1 Voltage transformers • According to IEC 60 044-2 / VDE 0414-44-2 Technical data The technical data of the current and voltage transformers are given in the associated order documents. 7.10 Protection and control equipment Protection and control equipment is equipped according to the customer’s specifications.

A coupling magnet, which is fitted to the bottom end of the measurement box, transmits its position to an armature outside the switchgear vessel through the non-magnetizable switchgear vessel. This armature moves the ready-for-service indicator of the switchgear. While changes in the gas density during the loss of gas, which are decisive for the dielectric strength, are displayed, changes in the relative gas pressure resulting from temperature and external pressure variations are not. The gas in the measurement box has the same temperature as that in the switchgear. The temperature effect is compensated via the same pressure change in both gas volumes. 38 Revision 06 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * 500-8384.9 Description 7.13 Short-circuit/earth-fault indicators All ring-main feeders can be optionally equipped with a 3-phase short-circuit or earthfault indicator.

After completion of a closing operation, the closing solenoid is de-energized internally. It is available for AC or DC voltage. Power consumption: 140 W or 140 VA. Shunt release Shunt releases are used for automatic or deliberate tripping of circuit-breakers. They are designed for connection to external voltage (DC or AC voltage). They can also be connected to a voltage transformer for deliberate tripping. Shunt releases based on two principles (Y1, Y2) can be used: • With the shunt release (Y1) the circuit-breaker is opened electrically. Power consumption: 140 W or 140 VA. • With the shunt release (Y2) the electrical opening command is transferred magnetically and thus, the circuit-breaker is opened. Power consumption: 70 W or 50 VA. 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 49 Description Undervoltage release Circuit-breaker tripping signal C.t.-operated release (Y6) Undervoltage releases are tripped automatically through an electromagnet or deliberately. The deliberate tripping of the undervoltage release generally takes place via a NC contact in the tripping circuit or via a NO contact by short-circuiting the magnet coil. With this type of tripping, the short-circuit current is limited by the built-in resistors. Power consumption: 20 W or 20 VA. When the circuit-breaker is tripped by a release (e.g. by protection tripping) there is a signal through the NO contact -S6. If the circuit-breaker is tripped deliberately with the mechanical pushbutton, this signal is suppressed by the NC contact -S7. The following c.t.-operated releases are available: • The c.t.-operated release 3AX1102 consists of an energy store, an unlatching mechanism and an electromagnetic system. Rated tripping current: 0.5 A/1 A • The c.t.-operated release 3AX1104 (low-energy release) is adequate for a tripping pulse of ≤ 0.1 Ws in connection with adequate protection systems. It is used if auxiliary voltage is missing, tripping via protection relay. Low-energy magnetic release (for type 2) Varistor module For tripping pulse 0.02 Ws, tripping via transformer monitor (IKI-30).

For site altitudes above 1000 m (above sea level) the standards do not provide any guidelines for the insulation rating, but leave this to the scope of special agreements. All parts housed inside the switchgear vessel which are subjected to high voltage are SF6-insulated against the earthed enclosure. Site altitude The gas insulation at a relative gas pressure of 50 kPa (= 500 hPa) permits switchgear installation at any desired altitude above sea level without the dielectric strength being adversely affected. This also applies to the cable connection when using screened cable T-plugs or cable elbow plugs. A decrease (reduction) of the dielectric strength with increasing site altitude must only be considered for panels with HV HRC fuses as well as for air-insulated metering panels and a site altitude of 1000 m above sea level. A higher insulation level must be selected, which results from the multiplication of the rated insulation level for 0 to 1000 m with the altitude correction factor Ka.

The transformer protection table below shows HV HRC fuse-links recommended for transformer protection. Furthermore, the switchgear also permits fuse protection of transformers up to ratings of 2000 kVA. Please contact us for such applications. The protection table applies to: • Maximum ambient air temperature in the switchgear room of 40°C according to IEC 62 271-1 considering the influence of the switchgear enclosure • Requirements according to IEC 62271-105 • Protection of distribution transformers according to IEC 60787 • Rated power of transformer (no overload operation) The specified HV HRC fuses make SIBA are type-tested partial range fuses according to IEC 60 282-1. The dimensions correspond to DIN 43625. The HV HRC fuses have a thermal protection in form of a temperature-limiting striker tripping operating in case of defective HV HRC fuse-links or high overload currents. Please contact us if you want to use HV HRC fuses from other manufacturers. Basis for selection of HV HRC fuse-links: • IEC 60282-1 • IEC 62271-105 • IEC 60787 • Recommendations and data sheets of fuse manufacturers • Permissible power loss in the switchgear enclosure at an ambient air temperature of 40° C 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 55 Description Transformer protection table: Recommendation for the allocation of HV HRC

Fig. 48: Roller lever a at the auxiliary switch s of the ready-for-service indicator Fig. 49: Pointer position after operation of the plastic part at the auxiliary switch 11.6 Preparing the foundation Please observe the following items when preparing the foundation: • A suitable foundation can be a false floor, a double floor or a reinforced-concrete foundation. The reinforced-concrete floor must be equipped with foundation rails for supporting the panels. • As for design and construction of the foundation, the relevant standards DIN 43 661 “Fundamentschienen in Innenanlagen der Elektrotechnik” (Foundation rails in electrical indoor installations) and DIN 18 202 “Maßtoleranzen im Hochbau” (Blatt 3) (Measuring tolerances in structural engineering (Sheet 3)) apply. • The dimensions of the floor opening and the fixing points of the switchgear frame are given in the switchgear documentation. • Determine level differences between the installation surfaces of the panels using a measuring sheet, and compensate them with shims. 70 Revision 06 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * 500-8384.9 Installation Stipulations for evenness and straightness a Total switchgear width Fig. 50: Measuring sheet for the foundation. Evenness/straightness tolerance according to DIN 43661: 1 mm per 1 m length, 2 mm for the total length. 11.7 Comments on electromagnetic compatibility To achieve appropriate electromagnetic compatibility (EMC), some basic requirements must be observed while erecting the switchgear. This applies especially to the installation and connection of external cables and wires. Basic measures for ensuring EMC are already taken during design and assembly of the switchgear panels. Among other things, these measures include: • the low-voltage compartment is an integral part of the panel, which means that the protection and control devices with the internal wiring are metal-enclosed; • reliable earth connections of the frame parts via toothed contact washers or locking washers; • inside the panel, wires are laid in metal ducts; • spatial separation of sensitive signal wires from wires with high interference voltage levels; • limitation of switching overvoltages of inductive loads (e.g. relay or contactor coils, motors) by means of protective circuits with diode, varistor or RC element; • within the LV compartment, the secondary devices are mounted in defined zones; • shortest possible connection between corresponding modules in subracks; • consideration of the magnetic leakage fields of conductor bars and cables; • protection of subracks and wiring backplanes against interference by perforated shielding plates; • large surface bonding between all modules and devices as well as bonding to the earthing conductor of the switchgear assembly. These measures basically enable proper operation of the switchgear itself. The planner or operator of the switchgear must decide whether additional measures are required depending on the electromagnetic environment where the switchgear is installed. Such measures must be implemented by the installation company in charge. In an environment with heavy electromagnetic interference it may be necessary to use shielded cables and wires for the external connections in order to avoid interferences in the low-voltage compartment and thus, undesired influences on the electronic protection and control or other automation devices. Cable shields must be electrically bonded to be able to carry high frequencies, and contacted concentrically at the cable ends. The shields of cables and wires are connected and earthed in the low-voltage compartment. 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 71 Installation Connect the shields to earth potential - with high electrical conductivity and all around as far as possible. Protect the contact surfaces from corrosion in case of humidity (regular condensation). When laying cables into the switchgear assembly, separate the control, signaling and data cables and other lines with different signal and voltage levels by laying them on separate racks or riser cable routes. Corresponding to the different shield designs, there is a number of methods to perform connection. The planning department or site management determines which of the methods will be used, taking EMC requirements into account. The preceding points should always be taken into account. The shield is connected to cables or wires with clamps contacting all around. If low demands are placed on EMC, it is also possible to connect the shield directly to earth potential (combine or twist the shield wires) or via short cable connections. Use cable lugs or wire-end ferrules at the connecting points. Always keep the connecting leads of the shields as short as possible (< 10 cm). If shields are used as protective earth conductors at the same time, the connected plastic-insulated lead must be marked green/yellow over its entire length. Non-insulated connections are inadmissible. 12 12.1 Switchgear installation Tools/auxiliary means • Standard tools, such as a torque wrench • Compensation shims with a thickness of 0.5 – 1.0 mm for floor unevenness • Soft, lint-free cloths DANGER!

ATTENTION! Please observe the following for room planning and switchgear installation: Ö Dimensions of floor openings according to the dimension drawing in the switchgear documentation. Ö Direction of pressure relief according to the height of the cable basement in accordance with the cable bending radius. Ö Relief rooms according to the dimension drawing in the switchgear documentation. Room planning Switchgear installation There are two installation possibilities: • Wall-standing arrangement • Option: Free-standing arrangement Switchgear dimensions Switchgear dimensions (see Page 52, "Switchgear versions - Dimensions and weights") Pressure relief In the standard design, the pressure is relieved downwards. For further information, see Page 82, "Pressure relief options ". Room dimensions See the dimension drawings below. For the internal arc classification according to IEC/ EN 62271-200 / VDE 0671-200, the room height of accessible switchgear rooms results from the switchgear height of +600 mm (±100 mm). Door dimensions The door dimensions depend on - the number of panels in one transport unit - the switchgear design with or without low-voltage compartment Switchgear fixing • For floor openings and fixing points of the switchgear, see Page 75, "Floor openings and fixing points". • Foundations: - Steel girder construction - Reinforced-concrete floor Panel dimensions Weights Fixing options For binding switchgear dimensions, please refer to the order documentation (dimension drawing, front view). For data, see Page 52, "Switchgear versions - Dimensions and weights". Ö The switchgear must be fixed to the foundation so as to guarantee sufficient pressure resistance. The panels can be fastened to the foundation in the following ways: • Bolted to foundation rails. • Welded to foundation rails. • Screwed into the concrete using size 10 dowels if there are no foundation rails available. 500-8384.9 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * Revision 06 73 Installation We recommend to fasten the switchgear with at least 4 bolts size M8 in each panel. Ö The base pieces of the panel frames contain cutouts for fastening the switchgear (see dimension drawing). a Strain washer M8 (according to DIN 6796) s 3D washer M10 (according to DIN EN ISO 7093) Fig. 51: Switchgear fastening to the foundation Fastening the switchgear to the foundation Fasten each panel to the foundation as follows: Ö For direct fastening to the concrete, drill holes in the foundation and insert size 10 dowels. Ö Place shims in the spaces between the panel frame and the foundation in the area of the fastening cutouts, so that the switchgear is not distorted when it is bolted on, and the seam does not cover any air-filled gaps when the switchgear is welded on. Ö Bolt or weld the switchgear to the foundation. Ö Remove any dirt, as extreme cleanliness is required during installation. Ö Paint welding seams to protect them against corrosion. 74 Revision 06 * INSTALLATION AND OPERATING INSTRUCTIONS 8DJH * 500-8384.9 Installation Floor openings and fixing points These examples show a recess in the subframe, which is required for switchgear with cable-type current transformers and a height of 1400 mm.

(There have been no changes as against the old standard VDE 0681 Part 7 regarding the interface conditions, so that the corresponding indicators can still be usedn.) Ö Perform repeat test of interface conditions at the capacitive interfaces, as well as on the indicators according to the customer’s specifications or national standards. Ö Do not use short-circuiting jumpers as separate plugs. The function of the surge arrester installed is not guaranteed anymore if short-circuiting jumpers are used (see Page 33, "Voltage detecting systems"). Safe isolation from supply can be verified either with an HR or LRM voltage indicator or with a CAPDIS system. HR/LRM system a s d f g Cover for test sockets Earth socket Capacitive test socket for L2 Voltage indicator type HR, make Horstmann Documentation to repeat test of interface condition Ö Remove covers from capacitive interface. Ö Insert voltage indicators in the test sockets of the capacitive interface. If the indicator does not flash or light up in any case, the feeder is not live. The feeder can be earthed. If the indicator flashes or lights up, the feeder is live. Ö Refit covers of capacitive interface to protect it from pollution. Indications CAPDIS -S1+/-S2+ 204 Ö Verify safe isolation from supply on the display of CAPDIS-S1+/-S2+ (see Page 33, "Voltage detecting systems").

Cable testing with connected cables represents a special stress for the isolating distance. If the busbar of the switchgear under test or the opposite substation are live with operating voltage, adequate measures must be taken in order to prevent overvoltages. Normally, the switch-disconnector is not interlocked during the cable test. Ö Fit switching prohibition signs. Ö Secure the locking device (option) with a lock. ATTENTION! In cable panels type K (E), the switching operation for the EARTHED position has no influence on the voltage state of the radial cable behind the screwed-on cable compartment cover. Ö Before removing the screwed-on cable compartment cover, isolate and earth the radial cable in the opposite substation. Isolating and earthing the feeder under test Ö Disconnect the feeder under test. Ö Make sure that the feeder in the opposite substation has also been isolated and secured against reclosing. Ö Verify safe isolation from supply. Ö Earth the feeder. Preparations Ö Remove the cable compartment cover. Ö Undo the screw-type cone at the T-plug or at the adapter. Ö Fit cable test equipment (e.g. measuring bolts) according to the operating instructions of the plug manufacturers.
